Encysive Pharmaceuticals Announces Launch of Thelin (Sitaxentan Sodium) in Republic of IrelandFirst Selective, Once-Daily Oral Endothelin a Receptor Antagonist Now Commercially Available for Pulmonary Arterial Hypertension Patients
HOUSTON, April 2, 2007 (Healthcare Sales & Marketing Network) -- Encysive Pharmaceuticals (NasdaqGM:ENCY ) today announced the commercial availability of THELIN(r)(a)(sitaxentan sodium(b)) 100 mg tablets in the Republic of Ireland for the treatment of pulmonary arterial hypertension (PAH). The Company received European Union (EU) marketing authorization for THELIN from the European Commission in August 2006. THELIN is the first selective endothelin A receptor antagonist and the first once-daily oral treatment available for patients with PAH. THELIN will be available through the High Tech Scheme in Ireland.
THELIN is indicated for improving exercise capacity in PAH patients classified as World Health Organization (WHO) functional class III. Efficacy has been shown in primary pulmonary hypertension(c) and pulmonary hypertension associated with connective tissue disease (CTD).
``Clinical results demonstrate that THELIN can safely and effectively help later-stage primary and CTD-associated PAH patients manage their symptoms,'' said Sean Gaine, M.D., Consultant Respiratory Physician, Pulmonary Hypertension Unit, Mater Misericordiae University Hospital, Dublin, Ireland. ``THELIN also possesses two attractive characteristics: it is orally administered and requires only once-a-day dosing, which provides patients with a simpler treatment regimen.''
``PAH can progress into an extremely debilitating condition, especially for patients in whom it is secondary to the connective tissue disease scleroderma,'' commented Ann Kennedy, Chief Executive Officer of the Irish Raynaud's & Scleroderma Society. ``We are working with physicians on earlier recognition of PAH symptoms and can not overstress the importance of evaluating CTD patients for this condition. Promising new treatment options are now available, but patients must be properly screened and diagnosed before they can take advantage of these therapies.''
The European Commission's centralized licensing procedure permits Encysive to market THELIN in all 27 member states of the (EU). THELIN will be launched in successive EU member states as local government approval for reimbursement is obtained.
THELIN(r) (sitaxentan sodium) Overview
THELIN is an endothelin A receptor antagonist, a small molecule that blocks the action of endothelin, a potent mediator of blood vessel constriction and growth of smooth muscle in vascular walls. Endothelin receptor antagonists may prove to be effective in the treatment of a variety of diseases where the regulation of vascular constriction is important. THELIN is 6,500-fold selective in the targeting of the endothelin A receptor versus the endothelin B receptor. Highly selective endothelin A receptor antagonism has been shown to increase blood flow and reverse vasoconstriction in human clinical pharmacology studies.

Important Safety Information
In placebo-controlled clinical trials, the most frequent adverse events that occurred in patients receiving THELIN, which were considered to possibly be related to THELIN treatment, were headache, peripheral edema and nasal congestion. Other adverse events that occurred in at least 2% of THELIN patients, at a rate greater than placebo and considered to possibly be related to THELIN treatment, included dizziness, constipation, epistaxis, flushing, international normalized ratio (INR) increase, insomnia, nausea, upper abdominal pain, vomiting, dyspepsia, diarrhea, fatigue, muscle cramp, and prothrombin time (PT) prolongation. THELIN is also associated with liver function abnormalities. Because THELIN inhibits the metabolism of warfarin and other vitamin K antagonists, a dose adjustment for these drugs is needed when co-administered with THELIN. THELIN and other endothelin receptor antagonists have potential for liver toxicity and are teratogenic. Testing of liver enzymes is required prior to the initiation of THELIN and monthly thereafter. THELIN should not be used during pregnancy unless clearly necessary. THELIN is contraindicated in patients receiving cyclosporine A, patients with mild to severe hepatic impairment (Child-Pugh Class A-C), patients with elevated liver aminotransferases prior to starting treatment (elevation in liver enzymes to levels greater than 3 times the upper limit of normal), lactating patients, or patients with hypersensitivity to the active substance or any excipients.
It is estimated that PAH afflicts approximately 100,000 to 200,000 people in North America and Europe. The disease is characterized by high blood pressure and structural changes in the walls of the pulmonary arteries, the blood vessels that connect the right side of the heart to the lungs. As these arteries become increasingly constricted, blood flow and oxygenation may be inadequate to meet the body's demands. Since the heart must then pump harder to overcome the resistance, patients are susceptible to heart failure.
